Diamond Sutra: Chapter 25

“Subhuti, do not say that the Buddha has the idea, ‘I will lead all sentient beings to Nirvana.’ Do not think that way, Subhuti. Why? In truth there is not one single being for the Buddha to lead to Enlightenment. If the Buddha were to think there was, he would be caught in the idea of a self, a person, a living being, or a universal self. Subhuti, what the Buddha calls a self essentially has no self in the way that ordinary persons think there is a self. Subhuti, the Buddha does not regard anyone as an ordinary person. That is why he can speak of them as ordinary persons.”
